1 Integrated Web Application Server for IBM i Dawn May dmmay@us.ibm.com Presentation created by Tim Rowe, timmr@us.ibm.com

2 IBM i integrated Web application server the on-ramp to the Web 2

3 Agenda Integrated Web Application Server Introduction What is it Why did we add this Why not just use WebSphere Application Server? How do I create one Simply of course Application deployment What is supported What is not supported How do I get my app deployed Database What is supported How do I use the support 3

4 Introduction IBM i integrated Web application server Goals IBM ifunctional enhancement The Web container in integrated into the operating system Easy to use Simplified access, deployment and management Small, less resources Positioned as on-ramp to the Web Replacement for AFS Tomcat 4

5 Introduction IBM i integrated Web application server What is it? Web container Based on the OSGI framework Supports application packaged in a WAR Runs IBM Technology for Java (32 bit) Supports Java Toolbox and Native DB drivers Web container for simple applications 5

6 Why is this important to IBM i? It runs on our smallest boxes Simple to use Easy to install part of the operating system (already included!) Easy to maintain - PTFs Starts very quickly (seconds) IBM admin interfaces have a place run No Tomcat No WAS system instance Replacement for Tomcat Allow us to do things like Web Services Server Web Query IBM Systems Director Navigator for i Generates new excitement for i 6

7 New stuff Integrated Web Services Server FTestFile UF A E Disk D ErrMsg01 S 20 Inz('End of file reached') D ErrMsg02 S 22 Inz('Error!

8 New Stuff IBM DB2 Web Query for i Powered By Information Builder s WebFocus What we had Query/400 (Query for iseries) Green screen report builder Not updated (much) in ~10 years NOW we have Web Enabled Query/400 reports Simple, web based report builders Multiple output formats (pdf, xml, html, etc) Excitement from Advanced capabilities in a web based report builder Business Partners Customers ISVs orders in 5 months 8

9 New Stuff IBM Systems Director Navigator New Web Console for IBM i Available in 6.1 on every IBM i partition Over 300 tasks have been enabled for the Web New function only available in Web console BRMS HA Performance Job Watcher Disk Watcher 9

10 Why WebSphere Application Server vs IAS Why use WebSphere Application Server Express V6.1 is still shipped with the operating system on 6.1 Express runs on both the 64 bit and 32 bit JVMs Need EJB Support Full J2EE architecture Heavy database usage High Availability 10

11 Web Application Servers on IBM i Integrated Web Application Server WebSphere Application Server Express WebSphere Application Server Network Deployment Integrated Entitled Fee Integrated with i5/os V5R4 Ships with Web Enablement for i5/os Separate product i5/os PTFs WebSphere ifix WebSphere ifix Access to DB2 for i5/os Yes Yes Yes Supports JSF, JSP, & servlets Yes Yes Yes Multiple Instances Yes Yes Yes JNDI name space connection One Multiple Multiple Full J2EE Support No Yes Yes Java Based Messaging Engine No Yes Yes Cross Platform No Yes Yes Advanced performance, management & high-availability No No Yes Cost Packaging Fixes Memory requirements ~40% less 11

12 Web Application Servers on IBM i J2EE application packaging Integrated Web Application Server WebSphere Application Server Express Partial (WAR or WAB files) Full (WAR and EAR files) WebSphere Application Server Network Deployment Full (WAR and EAR files) Web Service Yes Yes Yes Web-services engine Axis2 V1.3 Yes Yes Yes Administration and configuration Horizontal growth and automatic failover for high availability Connection pooling datasources IBM Web Administration IBM Web Administration for i5/os, Qshell, WebSphere Administrative Console for i5/os, Qshell No No Apache commons database-connection pooling 12 WebSphere connection pooling IBM Web Administration for i5/os, Qshell, WebSphere Administrative Console Yes WebSphere connection pooling

13 How do I get to it V5R4 5722SS1 5722SS1 5722DG1 30 Qshell 33 Portable App Solutions Environment *BASE IBM HTTP Server for i5/os Group PTF SF99114 Level JV1 8 J2SE bit Group PTF SF99291 Level GA Cumulative PTF Package 13

14 How do I get to it Port 2001 interface 14

15 Create Application Server Step a: Intro page 15

16 Create Application Server Step b: Select the type and version of application server to create 16

17 Create Application Server Step 1: Specify the name of the application server 17

18 Create Application Server Step 2: Specify Port range 18

19 Create Application Server Step 3: Specify HTTP Apache server info 19

20 Create Application Server Step 4: Specify User server will run under 20

21 Create Application Server Step 5: Sample applications 21

22 Create Application Server Step 6: Summary - Application Server tab 22

24 Manage Server Start, Stop, Properties, Applications, and Database Properties View Logs! 24

25 Manage Server - Properties Version of server i5 specific info Subsystem Job Name JVM 25

26 Manage Server Server Tracing Trace your application using normal Java tracing Trace the entire server & application -.level=finer Trace specific package name com.ibm.class.level=info 26

27 Manage Server View HTTP Server Work with the HTTP server associated with this app server Start/Stop Direct link to manage the server 27

28 Manage Server View Logs Click to launch new window for error log Notice new format! Common Base Event - CBE 28

29 Applications Install applications Click the Install button to launch the install application wizard 29

30 Applications Must be in a Web Application Bundle (WAB) Using the Web Admin GUI, we will support both WAB files and the more common WAR file Servlet, JSP & JSF based applications Most all ASF Tomcat applications, will run on IAS Reasons an application will not run on IAS Some WebSphere based applications use WebSphere specific functions and classes will not run on IAS WebSphere Host Access Transformation Services (HATS) Full J2EE support Note: Application dependencies need to be included in the bundle 30

31 Applications When the application is deployed, the WAR file is converted into a WAB a WAB is basically a WAR with a manifest file MANIFEST.MF contains data that the framework needs to correctly install and activate the bundle The MANIFEST.MF is located in the META-INF directory of the bundle project. 31

32 Install Application Install application specify location Use Browse to navigate to the location of your application! 32

33 Install Application Install application - Specify application options 33

39 Manage Installed Applications Specify additional classpaths for the application 39

40 Database Connections Terminology Database connection = data source/jdbc Data source: A data source represents a specific database that is used by one or more applications installed in your application server. Data sources provide connection pooling and a JNDI name which can be used by applications to access the data source Database connection: Database providers and connections are the vehicles used to tell the server how to access the database, what database to access, and where the database is located. It supports the native JDBC driver, IBM Toolbox for Java and JTOpen JDBC drivers. IAS Limitation Only 1 JNDI name JNDI name must be: jdbc/proxyds Applications must be modified to use this name 40

41 Database Connections Create connection Launch Wizard to create new connection Click Manage Database Conncetions 41

42 Database Connections Create connection Specify the database connection type IBM Developer Kit for Java JDBC driver - Local DB2 IBM Toolkit for Java JDBC driver - Remote DB2 Derby Database Provider - Local Specify Connection ID application uses this connection ID to access the database 42

43 Database Connections Using the Connection ID Note IAS JNDI name *DEFAULT InitialContext context = new InitialContext(); DataSource ds = (DataSource) context.lookup("jdbc/proxyds"); Connection con = ds.getconnection(); No Connection Info passed on Datasouce getconnection() Unique Connection ID InitialContext context = new InitialContext(); DataSource ds = (DataSource) context.lookup("jdbc/proxyds"); Connection con = ds.getconnection("myconnectionid", null); Unique Connection ID allow for multiple databases to be specified Unique Connection ID passed on the Datasouce getconnection() 43

44 Database Connections Create Connection Database location *LOCAL database is located on this system hostname of remote system database is located on Schema name Same of the schema, collection, or library for the DB2 database Connection user ID I5/OS User profile User must have authority to the database! 44
